Paul Eggert	0b97ffdf32	openat2: new module ... This supports the openat2 system call of Linux 5.6 (2020) and later. Although not yet exposed by glibc, the call is useful for programs like GNU Tar that need to be paranoid about traversing file names from untrusted sources. On platforms lacking openat2, it is emulated in user space. * lib/openat2.c, m4/openat2.m4, modules/openat2: * modules/openat2-tests, tests/test-openat2.c: New files. * lib/fcntl.in.h (struct open_how, RESOLVE_NO_XDEV) (RESOLVE_NO_MAGICLINKS, RESOLVE_NO_SYMLINKS, RESOLVE_BENEATH) (RESOLVE_IN_ROOT, RESOLVE_CACHED): New type and constants, if <linux/openat2.h> does not define. (openat2): New decls. * m4/fcntl_h.m4 (gl_FCNTL_H, gl_FCNTL_H_REQUIRE_DEFAULTS) (gl_FCNTL_H_DEFAULTS): * modules/fcntl-h (fcntl.h): Also check for openat2.	2025-10-27 17:11:50 -07:00
